My invention relates to overshoes of the excluder type wherein the legcovering portion is provided at each side with surplus inaterialinthe-form of forwardly extending expansible flaps which permitenlargement of the upper for inserting and removing the foot, theseflapsbeing detachably connected across the front of the overshoe to hold theupper or leg covering portion of the overshoe in contracted leg fittingform, and my present invention has reference'more particularly to theconstruction of the expansible side portions or flaps by providing foldsin the leg encircling portion of the upper so that these folds conformto, lie against and connect across the front of the overshoe.

The principal objects of my inventionare tov provide an overshoe of theexcluder type and method of making same wherein expansibility isprovided in an improved manner; to insure maximum enlargement of the legencircling portion with a minimum amount of material; to construct theupper with a one piece continuous facing around the leg por- 25 tion andjoinedtogether at the back and having fullness at the sides formingfolds for expansion and contraction which connect across the .frontofthe overshoe; to insure vulcanization and permanent shaping of thisfacing 30'blank in a neat form fitting manner by securing same to alining which is fitted snugly around the last and slitted aftervulcanization at the folds; and in general to provide an improvedovershoe *of the excluder type.

On the drawing:

Fig. 1 is a perspective view of an overshoe constructed in accordancewith my invention;

'Fig. 2' is a side view of the lining as assembled on the last;

Fig. 3 is an'enlarged sectional view on the line 3-'3 of Fig. 1; and rFig. 4 is an inside view of the assembled leg encircling blank fromwhich the expansion fol'dsare formed.

Referring to the drawing, the reference numeral 5 indicates the footportion of the overshoe, 6 the overshoe top, and 7 the upper portion ofthe. lining on which the parts are assembled, the lining being of formfitting 50-shape with slits 8 at the sides to permit en- 1931. Serialmpseamo.

iargement for inserting and removing the.

foot. The overshoe top 6, which is continuous across'the front and alongthe sides and joined together at the back, is adhesively secured toandof a form corresponding to the lining 7 except at the slits 8 wherethe overshoe top 6 has excess material providingfolds 9 to permitenlargement of the upper, and these folds normally extend forwardly fromthe respective slit 8 and lie compactly against the front portion of theovershoe upper, in which position their forward extremities :areconnected by the ladder type buckles 10 or any other suitable type offasteners.

This not only affords a neat and simple structure that is convenient tomanufacture, but it insures a dependable waterproof closure at theplaces where expansion occurs as the expansion members 9 are merelyfolds at intermediate places in a continuous upper blank which avoidsthe joints and seams that are customarily employed in making theexpansible portions of overshoes of thi-scharacter.

In constructing this overshoe, the lining, which preferably consistsofthe main section 7 and a toe covering section .11 joined together atthe front and down thesid-es by the tape 12, is stretched around thelast 13 and joined together at the back in the usual manner and hastheloweredge lasted over an insole (not shown) to afford a form fittingbodyupon which toassemble. the rest ofthe overshoe parts, the liningsections '7 and 11 being provided on the outer sides with a skim coating13 of rubber composition and the tape 12 being frictioned to facilitatethe uniting of the other overshoe parts therewith.

The blank which-forms the overshoe top 6 is then applied around thelegcoveringpor tion of the lining on the last, this blank having beenpreviously prepared in substantially the form shown in Fig. 4 with-afacing layer 14 of rubber on a layer of fabric 15 over the upper edge ofwhich latter the rubber 1a is turned as indicated at 16 to finish thetopedge of the overshoe, and this blank preferably having at each side ofthe middle, a fabric reinforcing-17 on the'inner sideat the location ofand in the form to line the fold 9 which is formed from the respectiveportion of the said blank.

in applying the blank of Fig. 4 to the lining of Fig. 2, the middleportion of the blank between the fabric pieces 17 is stretched on andadhesively secured to the front of the leg portion of the lining Z11with the gunnned forward edges 18 of the fabric 1'? ad hesively securedto the lining at the sides. The portions of the blank to which thereinforcing fabrics 1'? are attached are then folded substantially alongthe lines 19, whereupon the gummed rear edges 20 of the fabric pieces 17are adhesively secured to the lining 7 slightly to the rear of the linealong which the gumined edges 18 have been attached thereto, andthereupon the portions of the blank beyond the gummed edges 20 areadhesively secured to the lining, and the end edges of the blankoverlapped or otherwise secured together at the back of the lining.

The end edges of the blank may, if desired, be secured together beforethe blank is ap plied on the lining 711, in which event the blank, whichis then in a tubular form, is slipped down onto the leg portion of thelast which has the lining 711 thereon, and either the front or rearportion of the blank is first applied in the proper place on the liningand rolled down in adhesive contact therewith, after which the otherportion of the blank is located in proper position and rolled down inadhesive contact with the lining, the gummed edges 18 and 20 likewisebeing rolled down in adhesive contact with the lining, in whichoperation the gummed edges 18 and 20 of ach fabric reinforcing 17 arebrought close together in proper position on the lining, and theportions of the blank "etween the respective gummed edges 18 and 20being accordingly folded outwardly in tapered pocket form.

After the overshoe top 6 has been secured in place, the foot covering 5,which has a rubber facing corresponding to that of the overshoe top, isadhesively secured on the foot portion of the lining with the upper edgeof the foot covering overlapping the lower edge portion of the overshoetop 6 and rolled down firmly to insure a thorough sealing of the joint,said foot covering 5 preferably having a pointed portion 21 whichextends upwardly between the lower portions of the folds 9, and afterthis foot covering is secured in place, the sole 22 and heel 23 arebuilt up in the usual manner.

The folds 9 are provided with any suitable fasteners for detachablyconnecting the forward edges across the front of the overshoe, thesefasteners preferably being applied before vulcanization and employedduring the curing to hold the folds down in a close compactmanneragainst the front of the overshoe so that the folds will set invulcanization in the form that they are to assume when the overshoe isworn, the fasteners that I prefer to employ being of the ladder type, asshown at 10, with. attaching tabs 24 adhesively secured to the exteriorof the folds.

In preparing the overshoe for vulcanization with these fasteners, thesides of the folds that will come next to the front of the overshoe andthe front of the overshoe as well are thoroughly talcumed to preventadhesion in vulcanization, after which the folds 9 are drawn forwardlyand laid down snugly against the front of the overshoe and while in thisposition the tabs 2% of the fasteners 10 are adhesively secured to theouter sides of the folds 9 in position so that the fasteners, whenconnected, will hold the folds 9 in the desired compact form fittingmanner.

The overshoe is then vulcanized with the fasteners 10 connect-ed andholding the folds 9 in the desired position and after vulcanization thefasteners are released and the lining slitted at each side of the upper,substantially along the lines 8 of Fig. 2, between the places where theedges 18 and 20 of the respective fabrics 17 are secured to the lining,and this permits the folds 9 to open up and the overshoe upper to beexpanded and the overs ice to be removed from the last.

While 1 have shown and described my inadhesively securing a leg coveringblank onto- 1 the lining with the ends joined together at the back andwith a loose section of the leg covering blank at each side of the legportion of the lining in the form of a fold, then joining the foldsacross the front of the leg portion, then vulcanizing the overshoe andafter vulcanizing slitting the lining at each side of the leg portion atthe location of said folds.
